+    // Room lookup for the Tachyon voice server.
+    //
+    // Tachyon has NO room id on its wire - the client's voice ConnectionData carries only
+    // the AccountId (plaintext) plus opaque RSA blobs. So Tachyon resolves which room a
+    // speaker is in by asking us: GET /tachyon?id=<AccountId>, expecting a BARE numeric
+    // roomInstanceId in text/plain (see tachyon-server-master/src/room_lookup.cpp - it
+    // strtoull's the body and treats 0 / non-200 / non-numeric as "isolate this client",
+    // i.e. they hear no one). It scopes its Dissonance relay per returned room id.
+    //
+    // Set Tachyon's config  room_url = https://<host>/tachyon  (it appends ?id=<n>).
+    //
+    // Unauthenticated on purpose: room_lookup.cpp issues a plain GET with no token, exactly
+    // as the RecFlare reference does. The only thing exposed is which room-instance a given
+    // account is in, keyed on a numeric id we already hand out publicly; the id is validated
+    // as an integer before use. Returns "0" (nowhere) for anything we can't positively place,
+    // which fails safe: Tachyon isolates the client rather than leaking cross-room voice.
